Why is magnetoencephalogra phy (MEG) more useful than functional magnetic resonance imaging (fMRI) for studying participants' responses to quiet sounds?
 
  a. MEG equipment is much cheaper and easier to use than fMRI equipment.
 b. The magnets used in fMRI are very noisy, blocking the ability to sense quiet sounds.
 c. MEG recordings of brain activity must be taken more slowly than fMRI images, allowing a more accurate assessment of brain activity.
 d. Neither of these technologies is suitable for assessing participants' responses to sound.

Question 2

Magnetoencephalography (MEG) recordings may be taken
 
  a. at the same rate as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) scans.
  b. faster than positron emission tomography (PET), but more slowly than functional magnetic resonance imaging (fMRI) scans.
 c. faster than functional magnetic resonance imaging (fMRI), but more slowly than positron emission tomography (PET) scans.
 d. faster than both positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) scans.
